Effect of K. variicola on inflammatory cytokines and toll-like receptors (TLRs) expression of microglial cells. A Levels of mRNA expression of pro-inflammatory cytokines TNF-α, IL-1β, IL-6, and transcription factor NF-kB in microglial cells stimulated with different MOIs of K. variicola for 24 h. B Levels of mRNA expression of toll-like receptors TLR2, TLR4, and TLR9 in microglial cells stimulated with different MOIs of K. variicola for 24 h. (Three different experiments in duplicate, mean ± SEM, ANOVA, *p < 0.05, ** p < 0.01, ***p < 0.001, all comparisons were made to unstimulated microglial cells represented by the dashed line)
